Module 9

Module Objectives: (high priority standards *)

Understand that two events are independent if the probability of A and B is the product of their probabilities.

Understand conditional probability and interpret independence.

P(A/B) = P(A and B)/P(B)

Construct and interpret two way frequency tables of data and examine the independence of events.

Use data in various representations to recognize independence and conditional probabilities.

Find the conditional probability of A given B as the fraction of B's outcomes that also belong to A and interpret the answer in a model.

Apply the Addition Rule to compute probabilities of compound events.

P(A or B) = P(A) + P(B) - P(A and B)

Use probability to evaluate outcomes of decisions.
